Hayden's Hockey Room

This is Hayden's room. This was actually an "accident room" it was not made to be a bedroom, but the roof trellis was so high that the builder decided to make it a room. The two doors on either side are attic storage areas that I plan on closing in and making closets out of them. I believe that I just need some insulation, sheet rock - learn to do it, and I have two closets. Should be pretty straight forward. There are also two additional shorter doors that you don't see to the right and left at the bottom of the picture. Those are smaller attic storage areas. The round window you see is the only light into the room. It actually gives off too much light and it wakes Hayden up in the morning. As you can see, he is starting a collection of hockey pucks and using them to block the light. He also has "wallbangers" on his wall. To the right, you will see a hockey player named Ovechkin. This is Hayden's favorite player. Any ideas on this one too, would be much appreciated.
